ELEVATOR-DOOR HANGER.

Application filed June 11, 1921. Serial No. 476,793.

' To all whom it may concern:

7 Be it known that I, OSCAR P. MoGnE, a

citizen of the United States, residing at Dallas, in the county of Dallas and State of Texas, have invented certain new and useful Improvements in Elevator-Door Hangers, of which the following is a specification.

This invention relates to elevator doors and pertains more particularly to an'im-,

proved hanger for elevator doors and to the special and improved arrangement and construction thereof.

It is the principal object of the invention to provide an elevator door hanger which will allow of the freeand easy movement of the elevator doors, simply arranged and constructed and particularly designed so that the friction in its parts will be greatly reduced and where the Wear consequent to such friction present will be uniform, ob-

viating rough, uneven rolling surfaces such] as is usually the case, and further providing a true and level path upon'which thehanger rollers may travel in carrying the elevator doors.

Other minor but importantfeatures will become apparent and obvious by reference Referring more particularly to the draw ings, 1 denotes the side walls of an elevator well or shaft, and; 2 and '3 the elevator doors proper, 4. representing, a stationary or fixed door.

The hangers have a frame work consisting of a longitudinal back plate 5 by means of which the hangers are secured in position between adjacent side walls 1-.1, see Figure 3, of the elevatorshaft. Secured to the back plate 5 by means of the right-angled braces 6--6 and bolts 7-7 i an a gl bar 8 which parallels the back plate 5 about two-thirds of llZSdlStfl-HCB or length, see Figure 2, and

which bar'8 carries a grooved lower trackway 9, the same lengthas the bar 8,, the trackway 9 being bolted as at 10 to the angle bar 8.-; A plurality of roller bearings '11 11 properly spaced apart and connected by metallic strips 12-12are arranged to roll in the trackway i v 9 and a hanger plate 13 to which the doors carries a grooved upper member '15. The roller bearings 1111 being properly spaced .are attachedby means of'the bolts 14-14.," 1' i apart and connected by the strips 12-12 permit themember 15 to move easily and securely in the trackway 9. The bottom of the trackway. 9 has a rib or rail '16 and each therein, the rollers riding against the under s1de of the trackway' By this latter arof the hanger plates 13 has a roller18 set rangement the hanger plates are prevented from moving laterally and thus their dis The elevator doors may be hung with door 3 slightly in advance of the door'2 upon a trackway. extending the entire length-of the 1 back plate 5-, the angle bar supporting which trackway being shown-on thedrawing,\Fig fl Y ure 2, as 8...
